DYEING APPARATUS.

Application filed Apri1 8, 1926. Serial No. 100,486.

This invention relates to dyeing apparatus and the like, and aims toprovide means for impregnating predetermined parts of an ab-.

sorbent mass in the liquid.

A particular object of the invention is to provide a machine forspotting yarn while the yarn is wound in a mass of the type customarilyknown as a cone of yarn.

A device embodying the invention is especially adapted for impregnatingpredetermined parts of a cone of yarn with a. liquid such as water or anaqueous dyeing solution which does not spread readily in fibrousmaterial, although certain features of the invention may be applied alsowhen 'a rapidly spreading liquid such an alcohol dyeing solution isused.

' Particular objects of the invention'are to inject liquidsimultaneously at closely spaced points of the portion of the mass to bedyed, to inject liquid into separated portions of the mass in suchmanner that a portion of larger volume receives more liquid than aportion of less volume, and to insure the penetration of a substantialamount of the liquid into the part of the mass close to the core onwhich it is wound. In addition the invention provides an improved holderfor a cone of yarn.

The invention may best be understood by a detailed description of apractical machine embodying it. Such a machine is shown in theaccompanying. drawings, in which Fig. l is a plan view;

Fig. 2

provided with. a base plate B which may be supported at about the heightof an ordinary work bench by means not shown in the drawings. On theplate B are mounted a pump P and a. workholder W. In the opis a sideelevation of the pump showing parts sectioned on the line 2-2 of erationof the machine the pump draws liquid from a reservoir, .not shown in thedrawings, and forces it into predetermined portions of a cone of yarn onthe work-holder through injectors J, J mounted on a header H fixed tothe cylinder of the pump.

The pump P has a vertical cylinder P whose bore 1 is closed at its lowerend by a plug P- containing a drain opening P communicating with thevalve controlled drain pipe P extending through the plate B. The pistonP of the pump is driven from a shaft P mounted on the lower side of theplate 15 and driven through a punching press clutch so that it ma begiven a single revolution when desired y the operator. The piston isconnected 'with'a crank P on the shaft P by meansmf a lever P and aconnecting rod P 9. The rod P may be attached at different points of thelever P to vary the length of the stroke of the piston.

The inlet opening P of the pump cylin- \der is controlled by a checkvalve P which may be located in an intake pipe P connected to theopening P The. intake pipe P leads from a reservoir for the liquid dye(not shown) which may be located below the platejB.

The outlet opening P of the pump cylinder communicates directly with theheader H which is mounted on the cylinder.

The header H contains two crossingbores H H (lne end of the bore Hcommunicateswith the discharge opening 1? of the pump while the otherend is closed by a plug H. A. check valve H seated in the bore Hprevents the returnof liquid from the header to the pump during theup-stroke of the piston to the pump. The ends of the bore H are closedby plu s H", H, the latter of which is adjustable or a purposehereinafter explained. The bore H is rovided with two lateral openings HH in which are mounted the injectors J and J.

The injector. J comprises a triple nozzleagainst the front surface ofthe header H. In an enlarged bore in the front portion of the body J islocated a chuck J containing three longitudinal bores J whose outer endsform the discharge openings of the nozzle J To permit contraction of theinner portions of the bores J in order to grip the needles therein, therear portion of the chuck contains a diametrical slit J at the inner endof which is a transverse bore J extending across the three bores J, andtransverse slits J. The chuck J is retained in the body J by a nut Jwhich is screwed on the front end of the body and engages the chuck J soas to force the conical inner end J of the chuck against a conical seatin the body. The chuck J has at its outer end three projecting collarsJ" which are thrust into the mass to be dyed when the mass is broughtinto operative relation with the injector. On the outer end of the nut Jis an annular projection J lying some distance behind the outer ends ofthe collars J Each of the needles J has a solid rear end portion J whichis clamped in the inner portion of one of the bores J of the chuck byscrewing the nut J inward. As the shaft of the needle is of uniformdiameter, it may be gripped at any point by the chuck so that thedistance which it projects beyond the end of its collar J" may bevaried.

The needle J has a pointed front, whose apex J is on the axis of theneedle. The needle contains an open longitudinal groove J which extendsfrom the portion of the needle crossing the bore J, as nearly aspossible to the apex J The injector J is identical with the injector Jexcept that in the form shown its needles J have axial bores J extendingthrough their rear portions J instead of having solid rear portions likethe nee dies J The injector needles which have been described are notclaimed herein as they form the subject matter of my divisional aplication, filed March 14, 1927, Serial %o. 175,081.

The work holder W comprises a carriage 'W carrying a standard W in whicha shaft W is rotatably mounted. 0n one end of the shaft W is a coneholder WV adapted to carry a cone of yarn C by engagement with thecard-board core 0 on which such a cone is ordinarily wound.

' The cone holder W engages the core C of a cone of yarn only near itsends, thus leavinga free space inside the core. The cone holder has arod W of materially less diameter than thecore C of a cone of yarn.

carrying at its outer end an adjustable plunger W having afrusto-conical head W for engaging the core of such a cone at or nearits smaller end. -At the inner end of the rod answer W is a grippingmember W for engaging the larger end of the core. The member W has athreaded outer surface which forms a corresponding thread in the innersurface of the card-board core C when the core is screwed upon it.

The cone holder which has been described is not claimed herein as itforms the subject matter of my divisional application, filed March 14,1927, Serial No. 175,082.

The carriage W is reciprocable in directions parallel tothe needles J Jand adjustable transversely to the needles. The carriage is slidablymounted on rods W fixed on a frame W which is mounted on a transverserod W adjustably secured in standards i 11 projecting up from the plateB: A shaft W rotatably mounted in similar standards W assistsin'supporting the frame W and provides for reciprocating the carriage Won the rods W For this purpose the shaft W is provided with a gear Wmeshing with a rack W on the bottom of the carriage. A handle W isprovided for turning the shaft W The shaft W and the cone holder W arerotated through a small are at each reciprocation of the carriage bymeans of a ratchet wheel W'" fixed on the shaft W and a pawl W carriedby a bar W fixed to the outer ends of the rods .W Further rotation ofthe shaft W may be obtained by turning a hand wheel W also fixed on theshaft W.

In the use of the machine, the carriage W is first retracted to theposition shown in Fig. 1 and a cone of yarn O is mounted on the coneholder W N has been adjusted in accordance with the length of the conesto be dyed, a cone may be mounted on the cone holder very quickly andeasily as it is necessary only to slip its core .over the rod W and thenscrew the larger end of the core upon the threaded member W until theinner end of the core is brought into firm contact with the head W. Thecarriage is then moved towards the injectors by turning the handle Wuntil its movement is arrested by an adjustable stop W This causes theneodles J J to penetrate the yarn and forces the collars J into theouter portionof the yarn so as, to compress it above the outer ends ofthe needles, as shown in Fig. 3. The piston P of the pump is then givena single reciprocatory movement which forces liquid previously drawninto the cylinder of the pump through the header H and the injectors J,J into the portion of the cone of yarn immediately surrounding theneedles of the two injectors. The carriage W is then returned to theposition shown in Fig. 1. The pawl and ratchet WV, W cause aslightrotation of the cone C during the latter part of this movement. Theoperation is then repeated until two separated zones C C of the cone ofyarn are completely saturated with the dyeing soly spaced points, sothat the dyeing may be effected by means of the solution which does notspread readily, for example, an aqueous dyeing solution. Such a solutionmay be evenly distributed throughout the depth of the mass. This isaccomplished by the compression of the outer portion of the masssurrounding the needles by means of the collars J which prevents anexcess of liquid in the outer portion of the mass, and by extending theneedles so that the outer ends of their grooves J reach substantially tothe surface of the core of the mass. To accomplish this it may benecessary tolet the needles project so far that their apexes J enter thecore C as shown in Fig. 4, or

pierce the core, as shown in Fig. 3. This can be done without injury tothe needles, owing to the fact that the cone holder W leaves a freespace within the core into which the points of the needles may project.

A substantially-uniform saturation of the yarn in the two zones dyed isobtained by forcing a greater quantity of liquid into the zone C whichhas a larger diameter and consequently a larger volume than the zone CThe difference in the quantities injected into the two zones is obtainedby giving the liquid a freer passage to the grooves of the needles Jthan to those'of the needles J It will be noted that the liquid mayenter the grooves of the needles J directly through the axial bores J 22in the rear ends of these needles, while to enter the grooves of theneedles J the liquid must pass through the slot J" in the chuck so as toenter the grooves J 21 through the transverse bore J. The flow of liquidto the injector J may be further restricted to the exact extent desiredby means of the adjustable plug 'H, as clearly indicated in Fig. 4.
